Title: 固态夸克星？

Abstract: It is conjectured that cold quark matter with much high baryon density could be in a solid state, and strange stars with low temperatures should thus be solid stars. The speculation could be close to the truth if no peculiar polarization of thermal X-ray emission (in, e.g., RXJ1856), or no gravitational wave in post-glitch phases, is detected in future advanced facilities, or if spin frequencies beyond the critical ones limited by r-mode instability are discovered. The shear modulus of solid quark matter could be ~ 10^{32} erg/cm^3 if the kHz QPOs observed are relevant to the eigenvalues of the center star oscillations. Show Chinese abstract

Abstract: 据推测，具有极高重子密度的冷夸克物质可能处于固态，因此温度较低的奇异星应该是固态星。 如果在未来先进的设施中未检测到热X射线辐射的特殊极化（例如，RXJ1856），或在灾变后阶段未检测到引力波，或者发现了超过由r模式不稳定性限制的临界自转频率的自转频率，那么这种推测可能接近事实。 如果观测到的kHz QPOs与中心星振荡的本征值相关，那么固态夸克物质的剪切模量可能约为10^{32}erg/cm^3。
